FreeCache -- Making Universal Access Faster

Thanks to all who hosted a FreeCache.

FreeCache is a system of

To see a live snapshot of the FreeCache system go to the Status page.

The basic architecture is Real Simple(tm). It works entirely within existing technologies ("vanilla" web browsers and servers, http and https on the wire, plus a small cgi).

To use FreeCache, just click on a link like this. As a user you DO NOT need to install new software.

FreeCache works by moving content "hot spots" on the web closer to users. This provides several advantages to various parties involved: Users get faster downloads, content providers pay less for Internet-bound traffic, and ISPs pay less for Internet-originating traffic.

An example:
Say an up-and-coming rock band, the RockLobsters, has a website that has a large file, say http://www.rocklobsters.com/videos/my-new-rock-video.mpg that is 5MB-1GB in size. If it gets popular, they will lose their guitars and homes to their ISP because their bandwidth bill will shoot up.
Animaton of Web communication without FreeCache

Animaton of FreeCache communication

Please note that you cannot submit a whole site to FreeCache as in http://freecache.org/http://www.rocklobsters.com/ This will not work as only index.html will be cached. You have to prefix every item that you want to have cached seperately.

While FreeCache doesn't solve all bandwidth limitations, we hope it will alleviate a great deal of them.

We will have to further define the policies around the use of FreeCache. In the meantime, we reserve the right to exclude files or sites of files and exclude requestors for any reason.
